13\class TSQLClassInfo
14\ingroup IO

16Contains information about tables specific to one class and
17version. It provides names of table for that class. For each version of
18class not more than two tables can exists. Normal table has typically
19name like TH1_ver4 and additional table has name like TH1_raw4.
20List of this objects are kept by TSQLFile class.
